My present invention has to do with a bumper and bumper support of pecul ar structure, whereby there bumper of the bumperette type having a strong, rigid support, which can be conveniently manufactured in the factory,-so as to permit the sale and shipment of the assembled bumper and bumper support,

Furthermore, the bumper supporthas certain novel features, whichpermit its quick, convenient and easy mounting on automobiles of certain kinds for securing a max mum otrigidity and for insuring such strength in the support and bumper as to afford to the fenders and car parts efiicient protection.- I I I -With these and other ob]ects in view, my invention consists in the construction an rangcment and combination of the various parts ofmy bumper and bumper support,

whereby the objects contemplated are at-- tained, ashereinafter more fully set forth, pointed out in myclaims, and illustrated- 1n the accompanyingdrawings, in which:

For convenience, I have in Figures 1 to 3 inclusive shown a bumper and bumper support as constructed for and installed on a Graham-Paige automobile, Whilefm Figures 5 to 8 inclusive, I have shown the device. as installedon a Chrysler car.

is V provided a My present device consists of a bumper proper, a supportingmeans therefor, and in cidentally of means for conveniently connecting the supporting means to the bumper.

The bumper proper consists ofa pair of tubular members indicated generally by the reference numeral 10, the members ofthe pair being arranged-in vertically spaced, parallel relation, as shown in Figure 1. i

The bumper members 10 are of proper length for the car upon which they are to beinstalled, but generally speaking they extend from points about in line with the outer edge of the fenderslaterally and inwardly to overlap theback. portion of the car body (see for instance Figure 2). i

I find it desirable to slightly bend each bumper'membcr 10, as at 10 at a point nearer one .end than the other, so that the outer portion 10 of each bumper member 10 is inclined at an obtuse angle with relation to the main body thereof. 7

he portion 10" is designed to be adjacent tothe fender of a car when the bumper is in stalled on the car, and the inclination thereof.

with relation. to the main body 'of the bumper 10 is for the purpose of bringing the portion 10 a. littlev closer ,to the bumper for thus affording better protection. v For appearance sake,,and also toprevent rustat the ends of the members 10 and to close these members, so that they will not be so likely to catch obstructions, I provide each end of each bumper member 10 with a cap 12; Near the respective ends" of thebumper members 10, I provide clamping devices for connecting the bumpers 10 with the support hereinafter more fully described.

For convenience, I have given to the bumper proper the reference character A, to

the clamp members by which" the bumper members 10 are secured to the support the reference character B, and to the support itself the reference character C.

Each clamp B comprises broken ring members or straps 14 integrally connected onone side as at 16 and having overlapping ends as at 17 and 18. A bolt QOeX-tends through the connecting portion 16 and through the overlapping ends 17 and 18 and serves toconnect together the members 17 and 18 and to fasten them to the support C. I

The support C is: preferably made of a single piece of: heavy strap or bar iron. It cons'ists of a short, horizontalportion through which one of the'bolts is extended. The Extending from the portion 28 is a member,

portion 22 fits snugly against one of the memhere 17. From the portion 22, a portion 2% is inclined away from the bumper members 10 (see Figures 1 and 2) at such an angle that when the device is to be installed on a car, the portion 24 may be placed in horizontal position at .right angles to the longitudinal axis of the car, and thereupon the bumper 10 will be inclined from its outer end inwardly and rearwardly as shown in Figure 2. From that end of the portion 2% farthest from the members 10, a portion 26 is inclined tow: rd the members 10, and the other clamp device l3, and terminates in a short portion 28 parallel with the other portion 17 (see Figure 1.).

F rom the portion 28, a portion 30 extends away from the bumper 10 almost at right angles thereto, as shown in Figures 1 and 2, so that when the device is placed adjacent the rear end of the car, the portion 30 extends toward the car.

At what would then be the forward end of the portion 30, the material is twisted, so that the extreme forward end of the portion 30 forms a portion 32 inclined upwardly and forwardly.

I will. now refer to the manner of instal ling the bumper and bumper support above described upon a car, such for instance as a Graham-Paige.

Such a car has the longitudinal, side frame members 34 terminating in downwardly inclincd horns 36 at their rear ends. The rear portion of the horn 36 is provided with a flat face 38 in which is a transverse slot 40. A part of the member 24 is inserted into the slot 40 and a plate 42 is placed over the slot and secured to the horn by means of bolts 45. The depth of the slot 40 is slightly less than the thickness of the member 24, so that the plate 42 tightly clamps the'men'iber 24 in place.

The car is provided with a sheet metal member 4A, which covers the gasoline tank 4L6.

The member 32 is inclined upwardly slightly and secured by means of the bolt 4.7 to the lower, rear part of the member 44, as shown in Figures 2 and 4.

The members 24- and 26 thus form a truss for resisting impacts against the bumper, and

character C. It has the portions 22, 24, 26

and 28, similar to those already described.

4.8 projecting forwardly when the device is in position for installation, and terminating in an inclined end. 50.

The bumper and bumper support shown in Figures 5 to 8 are intended to be mounted on a car as shown in Figures 6 and l. the car is provided with the frame member 34., similar to the frame member 34 in general struc ture, having the horn 36, which has a rearwardly projecting lug 52, with a flat, rear face 54, in which is a transverse recess56 similar to the recess 40.

The member 24; is placed in the recess 56 and. fastened in position by means of a plate 4-2 similar to that already described, with bolts 41:5.

The Chrysler car has a member 58 forming i a protecting shield forthe gas tank. It also has a. tire carrier provided with a horizontal member 60 having a flange 62 riveted to the member 58.

The inclined portion 50 is secured to the flange 62 by means of a bolt 64.

The general structure involved in the two forms of bumper support is the same.
